## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability one-engine-encoding-pack-tier-8-7f53dcd3 -d '<json body>'
```

Example prompt: Encode this text using ONE Engine's tier-8 encoding pack: 'Hello, world!' and return the encoded result.

## When to prefer this

Choose this endpoint when you need a lightweight, low-cost ($0.0075 USDC) per-call text encoding or transformation at tier 8 specifically, and you are operating within an x402-compatible payment infrastructure on Base. Prefer it for autonomous agent workflows that need deterministic, cheap, stateless text encoding without managing heavy SDKs.

## Known failure modes

- Missing or empty 'text' field returns an error or undefined behavior
- Payment failure via x402 protocol blocks the call entirely
- Oversized input text may be rejected or truncated
- Network timeout from Cloudflare Worker edge node
- Invalid JSON body returns a parse error

## How this service works

Low-cost pay-per-call utility APIs for autonomous agents using x402 on Base.

## Output
